Tek 2465BCT CRT date codes

[NHnewbie]

I have recently acquired a spare CRT for my 2465BCT and am trying to understand the markings as follows:

P/N?: 154-0850-01
S/N?: 149403
Other?: 41-91 Is this possibly a date code, perhaps corresponding to week 41 of year 1991? If not, is there another meaning?

This CRT is used and I have no idea how much use it has had. In any event, seller described as "tested, working" and the price was right.

Thanks,

Why double post when you already have a current thread about this CRT?

Newer post, somewhat different topic.

They are both related to your Tek 2465BCT CRT(s), you could simply have asked it as a supplementary question in the thread that you had just posted a reply in.

Not a big deal but you already had a tuned in audience on that one.

Not a big deal

Apparently a big enough deal for you to notice and make two responses. I am not a Super Contributor like you, as can be seen from my very small number of posts, so not yet aware of the unwritten rules here. I'll try to be more careful in the future.

Hey, no offence meant, it really isn't a big deal - although it's useful to be aware that people round here do tend to be sensitive to double posting. None of us started out as super contributors you know (there's no way to avoid the title). When I read your OP I failed to notice that you were talking about a second CRT, not the one you already had in your 2465BCT.

With reference to your actual question, Tek can be a bit cryptic at times but it's quite feasible that it is a straightforward datecode - the scope was introduced in 1984.
